so my buddy just traded a busted ass da integra for a semi nice bagged 93 s10 with the 4.3 i know he should have done some research about the setup but he didnt and he is wondering what kind of mantaince is involved with them such as draing the tanks, lines and bags during the winter time and he needing any info he can obtain im not sure what all the brand names are of the parts all i know is that it has a motor driven compresser and 10 fun little switches and help tips and advice would be very helpful thanks
